Anti-scrape plastic package box

ABSTRACT

An anti-scrape plastic package box includes a plastic sheet, a connecting section, a figure layer and a cover layer. The plastic sheet has a first surface and a second surface opposite to each other. The connecting section is a flap section extending from one end of the plastic sheet. The connecting section is adhered to the second surface of the other end of the plastic sheet. After adhered to the other end of the plastic sheet, the plastic sheet becomes a receptacle enclosing an internal space. The figure layer is disposed on the first surface of the plastic sheet. The cover layer is formed of a hardening agent painted on the outer face of the figure layer.

BACKGROUND OF THE INVENTION

The present invention is related to a package box, and more particularly to an anti-scrape plastic package box printed with a figure.

A conventional paper-made package box is made from a paper sheet having an adhering side. The adhering side is adhered to the other side of the paper sheet to form a receptacle having an internal space. The outer surface of the paper sheet is printed with a figure as an advertisement or a description of the commercial product packaged in the box. The adhering side is adhered to an inner face of the paper-made package box so as to achieve a beautiful appearance without affecting the demonstration of the figure.

FIGS. 1 and 2 show another type of plastic package box 90 made from a transparent plastic sheet 91. One end of the plastic sheet 91 has an adhering side 92 which is adhered to the other end of the plastic sheet 91 to form a receptacle having an internal space. The plastic sheet 91 is also printed with a figure 93. The paint is uneasy to attach to the plastic material. In the case that the figure 93 is printed on the outer surface of the package box 90, the figure 93 tends to detach from the box to ruin the appearance when transferred, taken, etc. Therefore, the FIG. 93 must be printed on the inner face of the package box 90. Under such circumstance, in the case that the adhering side 92 is adhered to the inner face of the package box 90, the adhering side 92 is adhered on the figure 93. Due to the pulling force of the adhesive, the figure 93 is apt to peel off from the inner face of the package box 90. As a result, the adhering side 92 tends to detach from the inner face. Therefore, the adhering side 92 needs to be adhered to the outer face of the package box 90. Accordingly, the outer face of the package box 90 is unsmooth. Therefore, such package box 90 has a poor appearance and is easy to scrape a user. Moreover, in the case that the outer face of the plastic package box 90 is scraped, the figure 93 printed on the inner face will be fogged.

SUMMARY OF THE INVENTION

It is therefore a primary object of the present invention to provide an anti-scrape plastic package box which has an anti-scrape surface. Accordingly, the package box will not be abraded and can keep a good appearance.

It is a further object of the present invention to provide the above anti-scrape plastic package box which has better structural strength and can be more safely used.

According to the above objects, the anti-scrape plastic package box of the present invention includes a plastic sheet, a connecting section, a figure layer and a cover layer. The plastic sheet has a first surface and a second surface opposite to each other. The connecting section is a flap section extending from one end of the plastic sheet. The connecting section is adhered to the second surface of the other end of the plastic sheet. After adhered to the other end of the plastic sheet, the plastic sheet becomes a receptacle enclosing an internal space. The figure layer is disposed on the first surface of the plastic sheet. The cover layer is formed of a hardening agent painted on the outer face of the figure layer.

The present invention can be best understood through the following description and accompanying drawings wherein:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIGS. 3 and 4. The anti-scrape plastic package box 1 of the present invention includes a plastic sheet 12, a connecting section 14, a figure layer 16 and a cover layer 18.

The plastic sheet 12 has a first surface 22 and a second surface 24 opposite to each other. The plastic sheet 12 can be made of PVC, PET (Polyethylene terephthalate), PP or MILA material.

The connecting section 14 is a flap section extending from one end of the plastic sheet 12. The connecting section 14 is fixedly connected with the second surface 24 of the other end of the plastic sheet 12. After connected, the plastic sheet 12 becomes a receptacle enclosing an internal space in which an article can be contained.

The figure layer 16 is printed on the first surface 22 of the plastic sheet 12.

The cover layer 18 is formed of a hardening agent painted and adhered to the outer face of the figure layer 16 for preventing the figure layer 16 from being scraped or abraded. The cover layer 18 is made of a compound of a PU material such as PU and an isocyanate material such as polyisocyanate, which are mixed and hardened to form the compound.

The figure layer 16 is printed on the first surface 22 as necessary. The figure layer 16 can include colorful characters, pictures, etc. For example, the figure 16 can be a commercially distinguishable drawing, a product description or a colorful beautifying picture for attracting consumers.

The outermost layer of the anti-scrape plastic package box 1 of the present invention is the hardening cover layer 18. The middle layer is the figure layer 16, while the innermost layer is the plastic sheet 12. The outer hardening cover layer 18 serves to protect the middle figure layer 16 and the inner plastic sheet 12.

According to the above arrangement, the anti-scrape plastic package box 1 of the present invention has the following advantages:

-   -   1. Under the protection of the cover layer 18, the figure layer         16 can be disposed on the outer face of the package box 1. The         connecting section 14 can be adhered to the inner face of the         package box 1. The package box 1 of the present invention has         better structural strength and can be more safely used.     -   2. The cover layer 18 serves as an anti-scrape surface of the         package box 1 so that the package box 1 will not be abraded and         the package box 1 can keep a good appearance.     -   3. The plastic sheet 12 of the present invention can be         alternatively made of nontransparent material. It is freer to         choose the material of the plastic sheet 12 so that the cost for         the material can be reduced.

The plastic sheet 12 of the present invention can form a cubic body. Alternatively, the plastic sheet 12 of the present invention can form a cylindrical body.
